SHUTTLE HOLDER AND DRIVER FOR SEW|NGMACH|NES- Specification of Letters Patent.

1 Patented Jan. 30, 1906.

Application filed February 23,1905. Serial No. 246,873.

To all whom it may concern.-

Be it known that I, PATRICK J. HANLEY, a subject of the King of Great Britain, and a resident of Elizabeth, in the county of Union and. State of New Jersey, have invented a new and Improved Shuttle Holder and Driver '1 or Sewing-Machines, of which the following is a full, clear, and exact description.

This invention relates to improvements in sewing-machine shuttle holders and drivers of the type having an oscillating movement, the object being to provide a simple and novel means for holding the shuttle in position, doing away with the usual shuttlerace, and thereby obviating the friction incident to a shuttle operating in a race of the ordinary construction.

Other objects of the invention will appear .in the eneral description.

I will describe a shuttle holder and driver embodyin my invention and then point out the novel ieatures in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a face view o'f'a shuttle holder and driver embodying my invention. Fig. 2 .is a section on the line wt of Fig. 1. Fig. 3 shows the holder in plan. Fig. 4 is a sectional view showing the bobbin-case retainer.

Fig. 5 is an edge view of the shuttle. Fig. 6 shows a modified form of holder, and Fig. 7 is a plan thereof.

Referring to the drawings, 1 designates a shuttle-driver attached in the usual manner to a rock-shaft 2. The arms of the driver are provided on the outer side and at the opposite sides with lugs 3, which have tapped perforations for receiving pivot-screws 4, on which the holding devices 5 are mounted to swing.

In Figs. 1, 2, and 3 the holding devices which engage at the opposite sides of the shuttle 6 are substantially in the form of rings, and extended outward from one side are finger-pieces 7, between which a spring 8 is arranged to hold the holding devices yieldingly against the shuttle. I11 said Figs. 1, 2 and 3 the holding rings or devices have a swinging movement in the direction of the axis of the shuttle. In Figs. 6 and 7, however, the holding devices consist oi arms 9, which receive the shuttle at its upper and lower edges, the upper and lower arms bemg doubled and spaced apart, so as to engage against the inner and outer sides of the shuttle, and these arms 9 are held yieldingly in engagement with the shuttle by means of a spring 10, placed between the finger-pieces 11. A bobbin 12 is placed in the usual bobbin-case 13, which is mounted on a post 14-, arranged in the bobbin: The bobbin-case is held in position by means of a latch-plate 15, here shown as having swinging connection with a retaining-ring 16, depending from a front slide 17, on the bed-plate of the machine. .The latchplate 15 is held yieldingly against the bobbincase by means of a spring 18, and the said bobbin-case is held from rotary movement by means of a finger 19 thereon engaging in a notch 20, formed in the upper portion of the retaining-ring 16.

While I have described the latch 15 as attached to a retaining-ring, it is to be understood that it may be mounted on any other part of the machine. The shuttle 6 is provided in its edge with a circumferentially-disposed slot 21, through which the thread from the bobbin passes. This slot is quite long and permits of oscillating movements of the shuttle without drawing the threads away from the needle-opening. The thread is inserted into the slot 21 through an outwardlyopening slot 22, formed in the shuttle.

To remove the shuttle, the slide-plate 17 is to be drawn outward, and then by pressing the finger-pieces 7 or 11 toward each other the holding-rings will be spread apart, and then the shuttle may be readily removed or placed in position. Of course the bobbin-case may be removed without disturbing the shuttle or its holder.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A sewing-machine shuttle-holder comprising a driver, spring-pressed shuttle-holding devices on the driver, a bobbin-case removably placed in the shuttle, a finger on the bobbin-case, and a stationary part having a notch to receive said finger.

2. A sewing-machine shuttle-holder comprising a shuttle-driver, holding devices having pivotal connection with said driver and adapted for engaging with opposite sides of the shuttle, outwardly extending fingerpieces on said holding devices, and a spring arranged between the finger-pieces.

3. A sewing-machine shuttle-holder cornprising a shuttle-driver, spring-pressed holding devices mounted to swing on said driver and adapted for engaging with opposite sides In testimony whereof I have signed my to of the shuttle, a bobbin case removably name to this specification in the presence of placed in the shuttle, a retaining-ring desubscribing Witnesses.

pending from a slide-plate of the sewin nmchine, the said ring being provided ;ith a PATRICK HANLEY notch, a finger on the bobbin-case for engag- Witnesses: 5 ing in said notch, and a spring-pressed latch WILLIAM F. MARoH, on the retaining-ring for engaging with the J. P. KELLY,

bobbin-case. EDWARD J. HANLEY.
